Difficult loading of a second shot forced me to make a change. I shoot 300grain SST's at the range, (swabbing with a spit patch after each shot) During Inline season I start with the SST and use a 295grain Powerbelt for a follow-up if needed, they shoot almost identical to the SST at 50 and 100 yards and are easier to load that second shot.
I shoot exactly the same combination when hunting. This year I shot an elk with the SST and put a second one in with the 295gr. Powerbelt. Only difference from you is that I do not swab between shots but I am shooting Black Mag'3 which does not require it and my accuracy is good without the swab.
